Level dewatering screen（2）Upper compass screen surface（201）With lower compass screen surface（202）, the mud of screening enters one-level slurry storage tank（26）, cyclone
（3）Overflow enter middle storage tank（27）, middle storage tank（27）One-level slurry storage tank is given respectively（26）With processing mud pit（11）Fluid infusion；
More large batch of mud conditioning is realized by above step.
